Objective: The study was conducted to determine the caries experience and oral hygiene status of children suffering from attention deficit hyperactivity disorder (ADHD) and was compared with that of non-ADHD children.
Study design: A total of 80 children, including 40 ADHD and 40 non-ADHD children were included in the study. A visual dental examination for dental caries was performed and oral hygiene status of these children was determined. The parent/guardian completed a questionnaire concerning the child's behavior followed by questionnaire to the child regarding oral hygiene practices and food habits.
Results: Student-t test and chi-square test showed that children with ADHD had significantly higher defs score, mean plaque score in compared to that of non-ADHD children. Statistical significant differences were also found out in relation with frequency of tooth brushing and consumption of sugary food among the children suffering from ADHD.
Conclusion: Caries prevalence in the primary dentition is increased in the children suffering from ADHD due to poor oral hygiene and increased consumption of sugary foods.
